Laptop is working in safe mode, need it to work in normal mode. HELP!!

A friend needed to use my laptop. When she returned it to me, it is now working in safe mode. When I went to System Restore and uncheck the box that stated: Turn off System Restore, it said System Restore cannot be enabled in Safe Mode. Please restart you machine in normal mode and try again. But I can’t restart it in normal mode. PLEASE HELP ME!!
